Abstract

A diaphragm pump which has multiple discharge tubes and discharges fluid from each of the discharge tubes, includes: a powertrain housing; a motion conversion housing; and a pump housing which includes: a diaphragm frame having multiple diaphragms; a pressure frame; a separation frame; and a discharge frame. The pump housing further includes: a first flow channel leading from the first suction valve, the first pressure chamber, the first discharge valve, and the first discharge tube; and a second flow channel leading from the second suction valve, the second pressure chamber, the second discharge valve, and the second discharge tube.

What is claimed is: 
     
         1 . A diaphragm pump which has multiple discharge tubes and discharges fluid from each of the discharge tubes, comprising:
 a powertrain housing that provides rotational power;   a motion conversion housing that converts the rotational power received through the powertrain housing into a linear reciprocating motion; and   a pump housing that introduces and discharges fluid by the linear reciprocating motion provided by the motion conversion housing;   wherein the pump housing comprises:   a diaphragm frame having multiple diaphragms including a first diaphragm and a second diaphragm that are pumped by the linear reciprocating motion provided by the motion conversion housing;   a pressure frame having multiple pressure chambers including a first pressure chamber and a second pressure chamber in which fluid is introduced and discharged according to the pumping of each diaphragm;   a separation frame having multiple sets of suction valves and discharge valves including a first suction valve, a second suction valve, a first discharge valve, and a second discharge valve that control the fluid inflow and outflow of each pressure chamber;   a discharge frame having multiple discharge tubes including a first discharge tube and a second discharge tube through which fluid is introduced and discharged through each of the multiple discharge valves;   a first flow channel leading from the first suction valve, the first pressure chamber, the first discharge valve, and the first discharge tube; and   a second flow channel leading from the second suction valve, the second pressure chamber, the second discharge valve, and the second discharge tube.   
     
     
         2 . The diaphragm pump according to  claim 1 , wherein the powertrain housing comprises: a power frame that provides rotational force; a gear reduction frame that increases the rotational torque of the power frame; and a power shaft that provides the reduced rotation through the gear reduction frame to the motion conversion housing. 
     
     
         3 . The diaphragm pump according to  claim 1 , wherein the motion conversion housing is a rotating housing coupled to and rotated by the powertrain housing, and comprises: a rotating frame having a guide rail formed with a curvature and recessed along an outer circumferential surface; and bearings inserted into the guide rail; and reciprocating shafts connected to the Bearing at one end and the diaphragm at the other end; and the rotating housing that pumps each diaphragm by moving the bearings along the inside of the guide rail and making the reciprocating shaft perform a linear reciprocating motion when the rotating frame rotates. 
     
     
         4 . The diaphragm pump according to  claim 3 , wherein the rotating housing is comprised of: a fit hole through which the reciprocating shaft penetrates; and an anti-detachment frame that allows the reciprocating shaft to move only inside the fit hole; a diaphragm pump with multiple discharge tubes. 
     
     
         5 . The diaphragm pump according to  claim 1 , wherein the multiple nozzles connected to the multiple discharge tubes are characterized by further comprising nozzles having one outer nozzle and one or more inner nozzles. 
     
     
         6 . The diaphragm pump according to  claim 5 , wherein a mixed fluid channel is formed inside the outer nozzle and wherein the Fluid injected from the inner nozzle is sprayed into the inside of the outer nozzle and mixed with the fluid moving inside the outer nozzle to form a mixed fluid in the mixed flow channel. 
     
     
         7 . The diaphragm pump according to  claim 5 , wherein the nozzle outlet of the inner nozzle is characterized by being composed of multiple pores formed along the outer circumferential surface of the inner nozzle. 
     
     
         8 . The diaphragm pump according to  claim 5 , wherein the nozzle outlet of the inner nozzle is characterized by the formation of one or more venturi outlet having a narrower cross-sectional area. 
     
     
         9 . The diaphragm pump according to  claim 5 , wherein one or more vortex plates forming vortices are additionally included between the inner nozzle and the outer nozzle. 
     
     
         10 . The diaphragm pump according to  claim 5 , wherein the nozzle housing further comprises a brush head connected to the outer nozzle outlet; and the brush head comprises a head flow channel through which the incoming fixed fluid moves, and includes spray holes for the mixed fluid to be sprayed outward along the head flow channel.
